Created an attachment (id=101999)
 --> (https://bugs.webkit.org/attachment.cgi?id=101999&action=review)
proposed patch

Similar design than the last patch with the following improvements:
 * lots of refactoring
 * add a way to cancel pending tasks
 * schedule preloading on the main thread asyncronically through the event system (via WTF::callOnMainThread)
   in order to be able to initiate the load as soon as possible and minimalize the extra work that the parser
   need to do with preload scanning

It's still not fully ready since it's missing rebaselines for preload scanning tests.
Benchmark results are on their way, be patient. Feedback is greatly welcomed.
